Hot, hot, hot! Blake Lively opts for a daring see-through lace mini frock from Dolce & Gabbana Spring 2010 teamed with gold Christian Louboutin pumps at the New York City premiere of "Sherlock Holmes".

Style tip: Peek-a-boo lace that exposes undies looks to be a current trend among Hollywood's A-listers like Lively and Madonna. For an equally sexy but more modest take on the trend, wear a lacy blouse layered over a camisole in a matching color.
